Zero Trust Micro-Segmentation for Cyber Resilience

Traditional network security relies heavily on perimeter defenses, leaving internal networks vulnerable once an attacker gains access. As ransomware, insider threats and increasingly sophisticated attacks exploit unrestricted east-west traffic, enterprises need a more resilient security model that limits the impact of every breach.

This whitepaper explores how HCLTech's micro-segmentation approach strengthens security across Campus LAN and Data Centre LAN environments by enforcing granular, identity-driven policies at the workload level. Built on Zero Trust principles, it demonstrates how organizations can reduce attack surfaces, automate threat containment and improve compliance—without disrupting existing network operations.

Key takeaways:

• Contain breaches before they spread: Learn how micro-segmentation limits lateral movement by enforcing least-privilege access between users, devices and workloads, reducing the blast radius of cyberattacks.
• Accelerate Zero Trust adoption: Discover a reference architecture that integrates with existing NAC, SDN and security investments to deliver policy-driven segmentation across campus and data centre environments.
• Improve resilience and compliance: Explore how automated quarantine, enhanced east-west visibility and workload-level policy enforcement help strengthen cyber resilience while supporting regulatory and audit requirements.
